Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed September 21,1904. $erial No. 225,872.

To aZZ whom, it may concern:

Be it known that I, HOWARD B. SHERMAN, of Battlecreek, in the county ofCalhoun and State of Michigan, have invented certain new and usefulImprovements in Oil-Cups; and I hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, which form part of this specification.

This invention is an improvement in oilcups; and it consists principallyin the improved construction whereby the scutcheon which closes theoil-filling hole in the cup car-' ries a spring-finger which looks thead justingvalve. One of the advantages of this construction is that thescutcheon is less liable to jar open and allow oil to spill and thevalve is kept from jarring out of position or adjustment.

The spring and scutcheon are formed, preferably, in one piece, whichgreatly simplifies the construction and lessens the cost of the completecup.

The accompanying drawings illustrate a cup embodying my improvements,which I will now describe with reference to said drawings.

Figure 1 represents a central vertical section through the complete cup.Fig. 2 is a plan view thereof, showing the scutcheon closed in fulllines and open in dotted lines. Fig. 3 is a detail view of the D-shapedwasher, and Fig. 4 is a detail View of the scutcheon and springattached.

The cup proper may be formed of a glass cylinder A, a base-plate B, anda top plate C, connected by a central hollow spindle D. These parts maybe of ordinary construction.

The spindle D extends through an opening in the top plate G and slightlyabove the latter and is exteriorly threaded and engaged by a jam-nut E,by which the parts of the cup are held tightly together. The scutcheon Fis pivoted on or around the upper end of the spindle D, having anopening f for this purpose, and a washer Gr is interposed between thenut E and the scutcheon, said washer preferably having its apertureflattened at one side, as at g, to engage a corresponding flattened sided of the spindle, so that the washer cannot rotate. Consequently theoscillating movements of the scutcheon necessary to open and close thefilling-opening 0 in the top plate will not affect the .adjustment ofthenut E. The scutcheon will be held between the plate 0 and washer Gwith considerable frictional contact suflicient to prevent its beingjarred loose by the motion of the machinery to which the cup isconnected.

The opening in the spindle D communicates at bottom with a feed-passage6, leading through the part B, which passage 6 communicates at the baseof the spindle with the oilchamber through a lateral passage 6 justabove a valve-seat b, and this passage Z) is adapted to be closed by avalve h on the lower end of a stern H, which extends through the spindleD and has a screw-threaded engagement therewith above the valve, as atit, so that by rotating the stem H the valve can be forced to closeagainst the seat 6', or it can be adjusted so as to regulate the feed ofoil to the passage Z).

The stem H has a disk or head H on its upper end, which is provided withshallow vertical corrugations, as shown,on its edge, which corrugationsare adapted to be engaged by a tooth or projection f on a lockingspringF, which is attached to and preferably formed integral with thescutcheon F, as indicated in the drawings. This spring F, having itstooth f engaging the serrated edge of the disk H, will lock thevalve-stem and valve in any position in which they are adjusted and willprevent any displacement thereof by jarring movements, and the slightlateral movement of the scutcheon necessary to cover or uncover theopening 0 will not change the adjustment of the valve sufficiently toperceptibly alter the feed of the oil, even if the scutcheon should becarelessly left open. The movement of the scutcheon may be limited byprotuberances or pins 0 0 on the plate C, if desired, as shown in Fig.2.

The tooth f is sufliciently long to allow the valve to be adjusted oreven entirely closed without disengaging the disk from thelocking-finger, and while the bite of the tooth on the disk issufficient to prevent casual rotation thereof it willnot preventforcible rotation of the disk by hand in adjusting the valve, and thisadjustment of the valve is not suflicient to displace the scutcheon, asthe friction between the disk and the tooth f is less than the frictionbetween the scutcheon and the washer and top plate.

Moreover, the valve-stem being yieldingly locked to the scutcheon by thefinger, the valve will in turn prevent casual displacement of thescutcheon, and if the valve be firmly closed the scutcheon will bepractically locked and cannot be opened except by exerting considerableforce until the valve is Q a g mam loosened. Thus the valve andscutcheon are yieldingly interlocked by the finger F, and one cannot bereadily moved without moving the other. The scutcheon normally retainsthe valve in its adjusted position when the valve is opened, and in turnthe valve assists in retaining the scutcheon closed when the valve isclosed.

From the foregoing description it will be seen that I have a very simplecup provided with all necessary adjustments and with ineans for lockingthe valve in any adjusted position and for holding the scutcheonsecurely in its closed position and that no complicated or delicateadjustments are necessary in assembling the parts.

Having thus described my invention, what- I claim as new, and desire tosecure by Letters Patent, is

In combination an oil-cup having a central tubular spindle projectingthrough the top plate of the cup and exteriorly threaded, a scutcheonpivoted around the projecting end of the spindle and closing thefilling-opening in the top plate, a securing washer and nut on the upperend of the spindle, a regulatingwitnesses.
